Appendix 1Formulas of CFROI
Starting from the following formula
GI ¼ GCFanjCFROI þSV
1þ CFROIð Þn
we can demonstrate how the following alternative formulation of the CFROI canbe derived, if we assume in the calculation of economic depreciation a discountrate k = CFROI = r
CFROI ¼ Gross Cash Flow� Economic Depreciationð Þ=Gross Investment
Stating that:
ED ¼ economic depreciation ¼ GL� SVð Þ � snjr
where snjr ¼ ð1þ rÞn � 1½ �=r is the final value of an n-period annuity with interestrate r
multiplying each member of the above equation by (1+r)n and thereforesubtracting from each member GI, we can rewrite the relationship as follows:
GI ð1þ rÞn � 1½ � ¼ GCF � snjr � ED� snjr:
Being ð1þ rÞn � 1½ � ¼ r � snjr and anjr ¼ snjr � ð1þ rÞn; we can get
r � GI ¼ GCF � ED therefore r ¼ GCF � EDð Þ=GI quod erat demonstrandumð Þ

Appendix 2Excess Investor Return in Terms of EVA
According to O’Byrne (1997), we can express the excess investor return in year 1as follows: MV1 + FCF1 - (1 + k)MV0.
Expressing FCF (free cash flow) and MV (market value) in terms of EVA, wecan write:
MV0 ¼ cap0 þ EVA0=k þ ðð1þ kÞ=kÞX1
i¼1
x0DEVAi=ð1þ kÞi
FCFi ¼ NOPAT1 � Dcap1 ¼ EVAi þ kcap0 � Dcap1
MV1 ¼ cap1 þ EVA1=k þ ðð1þ kÞ=kÞX1
i¼2
x1DEVAi=ð1þ kÞi�1
where x0DEVAi and x1DEVAi are the investors’s expectations, at the end of year 0and 1, of EVA improvement in year i.
Collecting similar terms and simplifying, we obtain the following relation ofthe excess return in year 1:
ðð1þ kÞ=kÞð EVA1 � EVA0ð Þ � x0DEVA1Þ þ ðð1þ kÞ=kÞX1
i¼2
ðx1DEVAi � x0DEVAiÞ=ð1þ kÞi�1
Generalizing, we can express the n year excess return as follows:
ðð1þ kÞ=kÞð EVAn � EVAn�1ð Þ � x0DEVAnÞ þ ðð1þ kÞ=kÞX1
i¼nþ1
ðxnDEVAi � x0DEVAiÞ=ð1þ kÞi�n
